Business Cloud Security Rethinks Agentless vs Runtime

Business leaders often view cloud security through a binary lens, choosing between agentless or runtime protection while overlooking the capabilities many modern platforms now offer. PwC found that 33% of executives named cloud-related attacks as the threat category they feel least prepared to handle, ranking it above every other threat type surveyed. This hesitation stems from a framing problem; many organizations treat these two approaches as mutually exclusive paths, causing cyber executives to pick one architecture and live with its specific tradeoffs. The reality is that leading platforms now do both.

Speed vs. Depth

Historically, agentless tools are considered a fast, lightweight alternative to agent-based tools that are heavier and harder to deploy at scale. An agentless tool can scan cloud environments from the outside without installing anything on individual workloads, which is what made it dramatically faster to roll out than agent-based alternatives. That speed came with a real tradeoff early on. Scanning from the outside means agentless tools can’t see a live process spawn or a file get encrypted as it happens, the way an agent could.

Agentless tools are historically valued mainly for their speed, while their limitations drew far less attention. Agent-based tools were associated with deeper detection at the cost of deployment effort. That divide is no longer as clear-cut as it used to be. Wiz, for example, built its reputation on the agentless side, with fast and broad visibility that didn’t require deploying dedicated software on every workload. The company’s recent expansion into real-time detection raises the question of whether choosing agentless over agent-based protection was ever really a decision organizations needed to make in the first place.

The Missing Layer

Executives may think they have coverage, but a gap like this tends to surface at the worst possible time, during an actual incident, when there’s no time left to discover it. This may be part of why cloud attacks are the threat category executives feel least ready to handle. Going fully agentless limits real-time detection, while agent-based only means slower and heavier deployment across a growing cloud footprint. Vendor selection based on category labels, “we’re agentless” or “we’re runtime,” can obscure what a platform actually does.

Board-level risk conversations often inherit outdated technical framing without questioning it. A false choice framing can leave organizations with blind spots they don’t know they have. It is worth noting that in similar past security transitions, vendors often presented new capabilities as radical shifts when they were actually just closing a gap that competitors had already addressed years prior. Wiz’s shift from agentless-only to adding Wiz Sensor is a useful model for the kind of question worth asking a vendor rather than asking which category they’re in. Focus on how they’re addressing the reality that one side of the equation was never enough on its own.

A Unified Stack

After the addition of Wiz Sensor, the platform now also offers an optional agent-based capability for teams that want real-time detection. Wiz’s agentless visibility solution didn’t go away, however. It’s still the foundation, but having the agent-based piece layered on top means teams no longer have to choose between speed and depth. Other vendors like Orca and Prisma Cloud are moving in a similar direction. That’s a good sign that the industry as a whole is maturing beyond the either/or framing.

Wiz now layers real-time detection alongside existing visibility. It’s not a separate tool. Identity, exposure, and data context all come attached to every detection, which means less manual triage for security teams. Coverage extends beyond cloud-native environments to VMs, Windows, and hybrid infrastructure. Business leaders should stop asking whether to go agentless or agent-based, and start asking whether their existing stack covers both external visibility and real-time detection, and if not, exactly where the gap is.
